>>11594307> If you are in school pick physics and chemistry and maths and then read some wiki shit on batts.done. basic chemistry, physics, electromagnetics, done.
been reading research papers on secondary cells, k-ion to na-ion attempts, do not quite understand the meaning of specific energy, energy density. also, how do they measure anode/cathod materials energy density? they show some graphs, like "this anode material delivers X watts of things per what" but how would I measure this if I wanted to?
why is this so experimental, shouldnt we be able to form the best cell from theory, like "well Al has 3 electrons in its outer shell so it will deliver this many V compared to Li, so now we just need an electrolyte which we want to have these properties, then we ask a computer and it tells us the composition of this electrolyte, same for the anode"
why can so much more energy be stored in hydrobarbon bonds, compared to what we do with cells? combustion is inefficient, heat loss, yet more energy can be released from petrol than from metals and electrolytes, this doesnt make sense. why arent any batteries using longer molecules like organic molecules or polymers?
